Hello,
This patch set adds UDC support to the isp1760 driver, to be used with the
ISP1761 dual-role USB controller.
The first 21 patches rework the isp1760 driver to prepare it for UDC support.
In particular it removes the direct HCD dependencies from the glue code (02/22
to 08/22), creates core initialization code shared by the HCD and UDC (18/22),
move common initialization code to the core (19/22 to 21/22) and, finally,
adds UDC support (22/22).
The ISP1761 has three USB ports, with port 1 configurable in host or peripheral
mode with OTG support, and ports 2 and 3 supporting host mode only. OTG
support is not implemented yet, port 1 can thus be configured in host or
peripheral mode only.
The UDC driver has been successfully tested with the g_zero and g_mass_storage
gadgets.
The patches are based on top of v3.18-rc7.
Global changes compared to v1:
- Replace GPIO request move by patch 01/22
- Split PORT1 configuration to separate patch
- Drop the shutdown implementation patch
- Add patches 02/22, 04/22, 05/22, 13/22, 14/22
See individual patches for patch-specific changes.
